Antenna Structures and Electrical Components with Grounding

Apparatus, comprising:

• a first component mounted on a first flexible printed circuit;
• a second component mounted on a second flexible printed circuit;
• and
• a conductive fabric grounding structure that is interposed between the first flexible printed circuit and the second flexible printed circuit.

An electronic device, comprising:

• a metal housing;
• a dielectric antenna window mounted within the metal housing;
• an antenna carrier adjacent to the dielectric antenna window;
• antenna traces on the antenna carrier;
• a proximity sensor formed from at least one proximity sensor electrode that overlaps at least some of the antenna traces, wherein the proximity sensor electrode includes metal traces on a flexible printed circuit;
• and
• a transmission line that is coupled to the antenna traces, wherein the transmission line includes a positive signal conductor and a ground signal conductor in the flexible printed circuit and wherein the ground signal conductor is shorted to the metal housing.
